Poppy Dada is an American artist. As of 2002, she is a teenager in South Dakota. She is the creator of works such as "Deadly Midnight Snack," in which she placed an ancient Mayan carving. Nancy needed it to solve the Secret of the Scarlet Hand, so Poppy allowed her to replace it with one of her art dealer's, Taylor Sinclair's, old Oaxacan cookies. Poppy believes that art should be organic and should grow and change with each observer or consumer of it.She also met Elliot Chen at one point and gave him one of her paintings.
Her real name is Penelope Daddle, but no one in the art world or "anyone else who made it out of the 20th century" calls her that anymore.
